ABSTRACT Kaisa Tahvanainen Managing regulatory risks when outsourcing network-related services in the electricity distribution sector Lappeenranta 2010 176 p. Acta Universitatis Lappeenrantaensis 383 Dissertation. Lappeenranta University of Technology ISBN 978-952-214-913-8, ISBN 978-952-214-914-5 (PDF), ISSN 1456-4491 Deregulation of the electricity sector liberated the electricity sale and production for competitive forces while in the network business, electricity transmission and distribution, natural monopoly positions were recognised. Deregulation was accompanied by efficiencyoriented thinking on the whole electricity supply industry. For electricity distribution this meant a transition from a public service towards profit-driven business guided by economic regulation. Regulation is the primary means to enforce societal and other goals in the regulated monopoly sector. The design of economic regulation is concerned with two main attributes; end-customer price and quality of electricity distribution services. Regulation limits the costs of the regulated company but also defines the desired quality of monopoly services. The characteristics of the regulatory framework and the incentives it provides are therefore decisive for the electricity distribution sector. Regulation is not a static factor; changes in the regulatory practices cause discontinuity points, which in turn generate risks. A variety of social and environmental concerns together with technological advancements have emphasised the relevance of quality regulation, which is expected to lead to the large-scale replacement of overhead lines with underground cables. The electricity network construction activity is therefore currently witnessing revolutionary changes in its competitive landscape. In a business characterised by high statutory involvement and a high level of sunk costs, recognising and understanding the regulatory risks becomes a key success factor. As a response, electricity distribution companies have turned into outsourcing to attain efficiency and quality goals. This doctoral thesis addresses the impacts of regulatory risks on electricity network construction, which is a commonly outsourced activity in the electricity distribution network sector. The chosen research approach is characterised as an action analytical research on account of the fact that regulatory risks are greatly dependent on the individual nature of the regulatory regime applied in the electricity distribution sector. The main contribution of this doctoral thesis is to develop a concept for recognising and managing the business risks stemming from economic regulation. The degree of outsourcing in the sector is expected to increase in years to come. The results of the research provide new knowledge to manage the regulatory risks when outsourcing services.

13 1. Introduction At the beginning of the 1990s, the European electricity markets were liberalised. The objective of market liberalisation was to improve efficiency in the electricity supply chain, to decrease end-user prices and improve the quality of services. These goals were to be reached by promoting competition where possible, which in the energy sector meant deregulation of electricity generation and sale. Electricity network activities, electricity transmission and distribution, retained their monopoly status but were not unaffected by the liberalisation process. Network businesses have been regarded as a natural monopoly, in which competition is not considered feasible. Instead, networks are regulated in order to prevent network companies or distribution network operators (DNOs) from misusing their monopoly position to the disadvantage of their customers and to root out inefficiencies inherent in the business. Indeed, the changes in electricity markets have introduced pressure to cost and quality improvements. The design and scope of the regulatory system define the framework according to which the regulated activities are remunerated. Because of the high level of involvement, regulation is also a potential source of risk. Electricity distribution is a business characterised by its assets, which makes it particularly susceptible to economic regulation. A response from the industry to regulatory challenges has been to realign the strategic focus of the business. 1.1. Supply chain in the electricity sector Energy sector services have traditionally been characterised by public ownership and vertical integration. These elements were believed to secure society s basic services. Similarly as other infrastructure network industries, such as gas distribution, water and sewer services and district heating, electricity distribution networks typically constitute natural monopolies in their operating areas. However, the level of governmental intervention differs from one sector to another. The electricity distribution networks have two primary functions: to provide any electricity end-user with a reliable and reasonably priced access to electricity, and to form a marketplace for competitive electricity businesses, electricity generation and retailing, according to Figure 1-1. The gas distribution networks are faced with similar requirements (defined in the Gas Market Directive 2003/55/EC), although in many cases, the role of gas

14 networks is different from the role of electricity networks, for instance, in the sense that electricity is not storable. Water and sewerage systems and district heating networks typically lack the requirement to form a marketplace, mainly on account that competition is restricted for technical reasons. The design of these networks is based on consideration of the local needs and the local use of resources available. Electricity and natural gas supply on the other hand have national trunk lines, which enables efficient use of production capacity and competition on energy. Figure 1-1. Structure of electricity supply industry. In the electricity sector, the European Union legislation has defined the framework for market liberalisation, or deregulation, with the objectives of improving efficiency in the electricity supply chain, decreasing end-user prices and improving the quality of services (EC 2003b). Unbundling different functions of electricity supply is required in order to guarantee nondiscriminatory pricing and access to networks. For networks, deregulation of energy sector has, in fact, meant strengthening of regulation, a process often referred to as re-regulation.

15 1.1.1. Electricity distribution sector Electricity networks are regarded as natural monopolies on the premise that parallel networks in a distribution area are not considered efficient. Further, Gunn and Sharp (1999) define that a natural monopoly is sustainable if there exists a price and output combination such that entry by rival firms is unattractive, while all demand is satisfied and the revenues cover the total costs of production. The sector-specific authorities therefore grant an operating licence to a single distribution network operator to carry out electricity distribution service in its area. According to the Electricity Market Act (386/1995), the system operator shall maintain, operate and develop its electricity system and the connections to other systems in accordance with its customers reasonable needs, and to secure the electricity supply of sufficient quality to its customers. The Act also states among other things that the distribution system operator shall connect customers to the electricity distribution system and sell electricity transmission services for reasonable compensation. The costs for services in electricity distribution are raised in the distribution tariff, which makes up approximately 28 % of the household customer s electricity bill (EMA 2009a). Moreover, the power quality and reliability of electricity supply are to a large degree determined by the characteristics of electricity distribution networks. Electricity distribution is therefore an important component in the electricity supply chain. 1.2. Business logic in the electricity distribution business Electricity distribution companies have been granted monopoly positions and therefore do not face competition. Instead, regulation is relied on to produce competitive-like forces so that endcustomers receive electricity distribution services at reasonable prices and sufficient quality. The first aspect of regulation is therefore to protect the end-customers from the possible abuse of distribution companies monopoly position, mainly with respect to distribution tariffs. The customers also expect sufficient quality of electricity supply but are not willing to pay for excessive quality levels. While ensuring the reasonableness of regulated electricity distribution services in terms of price and quality, the regulator must provide companies with sufficient means to develop, maintain and operate the network in their areas of responsibility. In the literature on regulation, the holder of the network licence and the subsequent responsibility for providing electricity distribution services to end-customers are often differentiated from the owners (e.g. Viljainen 2005, Eyles et al. 2000, Mohseni 2003). Therefore, the third party

16 16 affected by regulation is the network asset owner. The owners of the electricity distribution assets want to make profit on their investment that is in line with the risk involved in the industry. The regulator s task is to evaluate the expectations of different stakeholders of electricity distribution and incorporate them into the regulatory regime, see Figure 1-2. Figure 1-2. Stakeholders of the electricity distribution business (Viljainen 2005). According to the directive 2003/54/EC, the national regulatory authorities must ensure that transmission and distribution tariffs are non-discriminatory and cost-reflective. Furthermore, the distribution tariffs should be sufficient to enable the necessary investments in the networks to be carried out in a manner allowing the viability of the networks. The directive does not, however, define any details on how these requirements should be included in the regulation of the electricity distribution business. Rather, the directive leaves room for different interpretations, which means that there are large variations in regulatory models in different countries; regulatory authorities have developed regulatory regimes based for instance on their unique economic, political and environmental conditions and needs. This also gives an insight into the electricity distribution operating environment; economic regulation is dynamic and can be regarded as an on-going process. Regulation is the primary means to enforce societal and other goals in the regulated monopoly sector. 1.2.1. Regulatory interaction One of the basic challenges in regulation of monopolies is the asymmetry of information between the regulated company and the regulator (e.g. Armstrong and Sappington 2005). Inevitably, the regulated companies have more knowledge over the regulator for instance about

17 17 the state of their networks, costs and their ability to carry out regulatory objectives, which the regulator cannot fully observe because of information asymmetry. The role of the regulator, on the other hand, is to encourage companies to provide the information for the purposes of setting and maintaining the regulatory regime. This interaction between the regulator and the regulated company is often referred to as a game. If a regulated company takes advantage of the information asymmetry, it can be considered gaming the regulator, or that the company behaves opportunistically or strategically (Jamasb et al. 2004, Gilbert and Newbery 1994). Exploiting the information advantage and optimising the regulatory outcome will maximise the company s profits. Therefore, the incentives and directing signals that are provided in the regulatory regime are important. However, the regulatory game is played by the guidelines of the regulatory framework. 1.2.2. Regulation approaches According to Parker (2003), a regulatory risk arises from the nature of the regulatory rules and practices. Or more precisely, the more rule based the regulation is, the less is the scope for regulatory discretion, which is one of the main sources of the regulatory risk, thereby placing great emphasis on the design and implementation of the regulation. Economic regulation is regarded in many instances as one of the single most influential factors in the electricity distribution business (Strausz 2009, Nordgård et al. 2003, DLA Piper 2008, Ernst&Young 2009). The distribution companies and the interested parties should therefore stay informed about the current regulatory practices and future development steps in regulation. Regulation on the electricity distribution business is primarily concerned with two main goals: the price of end-customer services and the quality the end-customers customers receive. Regulation limits the costs of the regulated company and also defines the desired quality of monopoly services. For the purposes of regulating end-customer prices, two main approaches can be distinguished: regulation of the profit of companies or the prices of monopoly services. In the profit regulation, the regulated company is allowed to collect costs for its services and a profit on investments in monopoly assets. Common examples of these kinds of cost-based regulation methods include cost plus regulation and rate or return regulation. Cost-based regulation methods consider regulation as a constraint of the firm s profit maximisation

18 18 (Kinnunen 2004). These models have been popular in the early stages of regulation, and in the pre-restructuring era (e.g. Jamasb et al. 2004), but they have been found inadequate for the purposes of modern regulatory regimes. Rate of return regulation is shown to encourage companies in overcapitalisation of the regulatory asset base (Averch Johnson effect). By increasing the regulatory asset base, the regulated companies expect a higher return. Another concern is that companies are not provided with incentives for cost efficiency. As a response to recognition of the information asymmetry problem, the regulation regimes have moved towards more incentive-based regulation or performance-based regulation (Joskow 2006, Jamasb and Pollitt 2000). The main idea in the incentive regulation methods is to utilise the information advantage that the regulated companies possess; the regulation provides the regulated companies with incentives to cut cost in the hope of retaining more profit for themselves by setting a ceiling for price or revenue. When there is no connection between the revenue cap and performance, maximising profit would mean the same as minimising costs. Price-cap and revenue-cap regulation are examples of these regulatory applications. As a regulation period usually extends over several years, the cost incentive is quite strong. Without additional quality regulation measures, these instruments eventually lead to quality degradation (Ajodhia 2002). Many regulation regimes therefore incorporate incentive schemes for the purposes of encouraging service quality. In fact, various incentive schemes are often included in price or profit regulation. Incentive schemes commonly employ yardstick regulation that rewards the regulated companies for their performance in relation to a benchmark, whether it is the performance of other companies or some other measure. A common characteristic for incentive-based regulation is that the regulation decisions are made before the regulation period (ex ante) so that the companies are aware of incentives. Incentive regulation has been found to be associated with a higher level of shareholder risk than the cost-based regulation (Alexander et al. 1996). Ex-post regulation evaluates the regulatory outcome afterwards and it is often regarded as being light-handed for giving more latitude to companies.

19 19 1.2.3. Other drivers Economic regulation is the primary means to promote common goals that originate from the prevailing EU legislation and the national legislations in the Member States. The focus is primarily on developing electricity networks as a marketplace, that is, network access conditions and charges, and on promoting the efficiency and quality of network-related services. The electricity distribution business has encountered some other drivers that are aimed at facilitating the functioning of the markets; one of these is the introduction of smart meters with the purpose of increasing competition in the electricity retail market. The network companies are usually the responsible party to manage the metering activity and consequently, to allow the end-customers to control their consumption and to improve energy efficiency. Actions taken to increase the use of renewable energy sources will also have an effect on electricity distribution networks, because the network will have to facilitate the resulting increase in the decentralised small-scale electricity generation units in distribution networks. Another type of drivers for the electricity distribution industry is the emerging environmental and safety concerns. For example, the impact of magnetic fields, employee safety issues, increasing value of landscape and restrictions on using detrimental chemicals are issues that need to be addressed in network planning and operation. For example Sweden has restricted pole climbing to promote employee safety, and new working methods have been introduced. Cabling electricity networks offers a solution to many of the problems (EC 2003c). The network assets are reaching the end of their lifetimes, and future networks have to be built to meet more demanding expectations. The technology available for building more sophisticated networks is developed, but often, investments may be too high or the technique is still too unreliable to use. Recently, a particularly strong value has been placed on customer service issues. Public concern over the reliability of electricity supply was instigated by the large disturbances around year 2000, and has since then compelled some authorities to set strict reliability requirements. As a result, distribution companies are formally expected to reduce the anticipated effects of climate change that will increase the occurrence of faults especially in overhead line networks. Society s pressure for reliable electricity supply is high and therefore, besides imposing

20 20 regulations, customer compensations for the loss of electricity supply are widely enforced. One common aspect can be observed; interruptions are now a factual cost item for the electricity distribution industry. According to Dean et al. (1999), changes in the business environment characteristics have often resulted in changes in business strategies and processes. Some of the external business drivers will have an indirect influence on the electricity distribution business but even more drivers will have a direct impact through the regulatory regime. The natural monopoly status of electricity distribution sets statutory and regulatory obligations and therefore has a decisive role in implementing new requirements for the business. As companies face more demanding legislative and regulatory requirements, an inevitable change in the strategic orientation of the business logic is to follow. 1.3. Outsourcing in the electricity distribution sector Literature recognises privatisation as the driving force in restructuring of the electricity distribution sector (Parker 2001, Ghobadian and Viney 2002) and, for instance, according to McAdam et al. (2003), in the U.K., privatisation has been the driving force for identifying processes of the network business, strategically re-organising the business and realising rapid improvements in productivity. Moreover, according to Bartle and Korosec (1996), contracting out is one form of privatisation. However, as Saplacan (2008) points out, among the main catalysts for business reorganisation have been the introduction of competitive forces in the electricity sector and resulting unbundling of operations. The primary means for increasing competition in the electricity distribution sector are economic regulation and reducing the size of the monopoly. As the two main foci of economic regulation have been cost efficiency and quality of supply, purchasing services from competitive markets would intuitively contribute to the directing signals of economic regulation. Hodemaeker and Meijden (2003) recognise the creation of commercial interfaces as a method to minimise regulatory intrusion. Contrarily, arguments against promoting competition by breaking up a dominant incumbent firm into competing units are that the cost advantages from economies of scale will be lost and while more competition is likely to improve allocative efficiency, it will be at the expense of productive efficiency.

21 21 During the last decade or so, the electricity distribution industry has witnessed a growing trend in outsourcing, where distribution companies are outsourcing their network-related activities. Main motivations for outsourcing of electricity distribution activities are often specified to be the increasing shareholder value, cost savings and focus on the core business (Eyles et al. 2000, Eurelectric 2003). For the Finnish electricity distribution sector, the expected benefits from outsourcing are better cost management and improved cost efficiency as well as access to additional resources and the possibility to focus on the core business (Aminoff et al. 2009). The tendency to outsource network-related activities raises a valid question of the factual monopoly activities in the electricity distribution business. For instance according to Viljainen (2005, p. 29), in the electricity distribution business, all the activities cannot be considered to possess monopoly characteristics. Harris (2006, p. 124) sees outsourcing of distribution-related services as a continuation of the unbundling process in the electricity supply industry. He goes on by stating that any (network) function that can be outsourced can be deregulated (Harris p. 129). Also in Eurelectric (2008), outsourcing is defined as a part of the restructuring process. For instance, in the U.K., the regulator is inclined to introduce competition into areas where it is in the interest of customers (Openshaw 2003). In fact, metering business has acquired economic significance, and is therefore unbundled from the network activities in the Netherlands and in the U.K. (Künneke and Fens 2006, Morch et al. 2007). But in most cases, there are no regulations concerning the reorganisation of the electricity distribution business. Rather, reorganisation of services is a method to respond to the new challenges of the changing operating environment: network companies have turned to outsourcing in order to achieve the efficiency and/or quality targets set by economic regulation. The extent to which outsourcing is employed will depend on the acceptable level of risk, which in turn is mainly governed by determinants of the regulatory framework. 1.4. Research design This thesis has two main areas of interest; economic regulation and outsourcing in the electricity distribution sector. Economic regulation is enforced in the industry to ensure the electricity distribution services for society. Economic regulation is the principal means to set goals for the electricity distribution therefore making the interaction between regulation and

22 22 industry drivers focal for the research. The risk from economic regulation arises from the fact that regulatory intervention in the business creates uncertainty in operating the electricity distribution business. Network construction and maintenance are commonly outsourced activities in the electricity distribution network sector, similarly as in many other infrastructure network industries such as telecom, water, district heating and gas distribution (Pedersini 2005). Because of the increased efficiency and quality requirements that will lead to the large-scale replacement of overhead lines with underground cables, the electricity network construction activity is currently witnessing revolutionary changes in its competitive landscape. Both the efficiency and quality demands originate from the economic regulation. As a result, the electricity network construction activity in its current state provides a good example to study the emergence and impacts of regulatory risks when network-related services are outsourced to specialised service providers. This is important because the degree of outsourcing in the sector is also expected to significantly increase in years to come. 1.4.1. Research questions and objectives The underlying research question in this doctoral thesis is how to manage regulatory risks when network-related services are outsourced to specialised service providers. This primary research question is approached by the following secondary research questions: 1) What are the risks stemming from economic regulation of the electricity distribution business? 2) In which way the distribution companies can respond to the regulatory risk? 3) What are the regulatory risks when employing a specialised service provider? The main objective of this research is to provide means to recognise and manage the business risks in the electricity distribution business stemming from economic regulation. In order to reach the main objective, this thesis analyses the characteristics of the operating environment in which the economic regulation plays a significant role. The analysis gives a basis for identifying the sources of risk for the electricity distribution operation. In particular, special attention is paid to the impact of risk that arises from regulating the quality of services provided by the electricity distribution companies. One of these main risks is due to the fact that

23 23 electricity distribution networks are vulnerable to adverse weather events; in the case of large disturbances, particularly the overhead line networks experience interruptions in electricity supply that may have large-scale consequences. This work assumes that the outsourcing of the network-related activities is increasing and that underground cabling is considered a feasible network construction method in areas traditionally regarded as unconventional. Therefore, the objective of this study is to recognise the regulatory risk when implementing outsourcing. The results of the research provide new knowledge for the management of the regulatory risk when outsourcing services in electricity distribution sector. 1.4.2. Research approach This doctoral thesis is the result of the five-year research at the Laboratory of Electricity Markets and Power Systems at Lappeenranta University of Technology. This thesis combines two research foci; economic regulation and business operations models in the electricity distribution industry. The scope of the research is chosen on grounds that both the service quality regulation and outsourcing will significantly affect the electricity distribution sector in the near future; the first one by defining the requirements for the quality of electricity provided for the end-users, and the second one by being the primary operations model by which most operations in the electricity distribution sector are carried out. Methods to assess the business risks of regulated monopoly companies already exist. The effects of various regulatory practices have been studied from the viewpoint of the systematic risk it imposes on valuation for the regulated companies (Alexander et al. 1996, Alexander et al. 2000, Binder and Norton 1999, Buckland and Fraser 2001, Paleari and Redondi 2005, Grout and Zalewskaja 2006). The studies on the risk exposure of the Finnish electricity distribution sector have relied on international references, as these studies require data from stock market listings, which for the majority of the Finnish distribution companies are not available (FIM 2004). Therefore, the emphasis of this research is on a far less investigated area of the regulatory risk; that is, the asymmetric features of the regulatory risk. The features of the regulatory regime often present an asymmetric risk defined in this thesis as an asymmetric distribution of possible outcomes that result from the regulatory practices and regulatory intervention and that are unique for each individual regulatory setting of the regulated companies. For instance, all the Nordic countries and other European countries have developed regulatory regimes based on their own requirements and needs, which has led to highly specific regulatory regimes.

24 24 The research questions require formulating a holistic view of the emerging regulatory risk and understanding its impact on outsourcing in a regulated industry. Therefore, the approach most suited for this research is qualitative. The data available from the research area and the nature of the research questions support the qualitative research approach. Moreover, the study belongs to the hermeneutic paradigm as this paradigm according to Gummesson (1991) concentrates on understanding and interpretation of the subject to be studied. More precisely, the study was carried out by applying the action analytical research method. Action analytical research provides a good platform to study dynamic features of regulatory interaction in the electricity distribution business. According to Olkkonen (1994), action analytical research seeks to gather information relevant for the research area, to interpret and analyse it and recommend changes in order to improve the practices and outcomes in the research area. This research approach provides means to recognise and manage the regulatory risks in a novel way; nevertheless, as it permissible to action analytical research approach verification of the results is left outside this study. The research questions are discussed according to the scheme presented in Figure 1-3.

25 25 First, for the analyses and classification of risks, a systematic approach is taken. That is, the risks are identified and their importance is evaluated according to predefined principles. Second, the methods are detected by which distribution companies can technically and organisationally prepare for the above-mentioned risks, especially in a case where revolutionary changes in the business environment are taking place. Finally, the effects of the regulatory risk when employing a specialised service provider for network construction are analysed by using electricity network underground cabling as an example. 1.4.3. Research data The results presented in this doctoral thesis have been drawn from the research that has mainly been carried out in four different research projects. This section gives a review of these projects and the role of the author in them. The research topic was first approached by examining the characteristics of the operating environment and economic regulation in the Finnish electricity distribution sector. The work was carried out by participatory research mainly in the following research projects: Developments of electricity distribution business (Partanen et al. 2004, Partanen et at. 2005) and Further development of the efficiency measurement model based on the DEA method (Honkapuro et al. 2006). The first project discussed the development opportunities of services business in the electricity distribution business as a response to future challenges. Outsourcing was acknowledged as a potential and effective business model. The outsourcing opportunities and restrictions were considered for individual activities in the electricity distribution value chain. The project used a scenario method for identifying the changes in the electricity distribution business operating environment. The author was involved in compiling the scenarios. The shift towards incentive regulation was considered a factor for innovative business solutions and the emergence of service markets. An observation of the regulatory development was the increased significance of quality regulation (Tahvanainen et al. 2004). The research data also allowed the comparison of the regulatory characteristics under different regulation models in the Nordic countries and revealed

26 26 that the risks associated with individual regulatory systems are different (Tahvanainen et al. 2005). The project (Honkapuro et al. 2006) examined the quality incentives for the Finnish regulatory regime and developed the efficiency benchmarking. The basis for analysis was data submitted to the regulator by distribution companies. The projects revealed that there is a need to further study the method in which the regulation impacts the regulated business and the directing signals it provides. Inadequate understanding of the regulation does not provide means to prepare for the regulatory risks. In this thesis, the regulatory risk is discussed from theoretical perspective in section 2.3. The real-life impacts of regulatory risk in the Finnish electricity distribution sector are presented in Chapter 3. With the developments in the regulation practices and the increased quality awareness resulting from large-scale disturbances, the quality regulation aspect was further emphasized as an interesting research area (Tahvanainen et al. 2007, Tahvanainen et al. 2008) Another strand of research focused on the emergence of new service provider markets from the re-organisation of the value chain in the electricity distribution industry. The project Challenges in infrastructure management business: Creating competitive advantage in emerging infrastructure network services market (Immonen et al. 2009a, Immonen et al. 2009b) produced a constructive framework for analysing the impacts of network companies changing strategic needs on valuable resource configurations of the service providers. The author of this doctoral thesis was one of the main authors in the project. The focus of the project was on the service provider business; however, recognising changes in the value chain is relevant also from the viewpoint of the distribution business. The results of this project comprised the basis for developing a management concept for underground cabling for the electricity distribution companies presented in the empirical part of this thesis. Outsourcing in the electricity distribution sector in Finland was studied at a more general level in the project Outsourcing services in electricity distribution network industry (Aminoff et al. 2009). The objectives of this project were to determine which network-related activities are purchased from service markets and what are the reasons for outsourcing; the project also analysed the expected benefits and risks of outsourcing, gathered experiences and indications of the future development in outsourcing volumes. The project provided information on the initial stages of outsourcing in the electricity distribution sector in Finland as discussed in Viljainen et

27 27 al. (2009). The questionnaires and interviews were used to seek out the best practices of outsourcing. Outsourcing experiences were gathered in a web-based inquiry, in which 30 companies out of 81 Finnish distribution network companies replied, see Trygg et al. (2009). The interviews conducted in both the distribution companies and the service providers provided in-depth knowledge on outsourcing in the sector. The results of this project are used in this thesis to give a general view of the present state of outsourcing in the electricity distribution industry in Finland and to explain some of the characteristics associated with outsourcing. The author of this doctoral thesis was involved in preparing the questionnaire and conducting the interviews. The author participated in analysing the results and was one of the main authors. The research work has partly been carried out in joint research projects with Tampere University of Technology, the companies in the Finnish electricity distribution industry, the Energy Market Authority and VTT Technical Research Centre of Finland. Numerous researchers representing the Departments of Electrical Engineering, Industrial Management (Technology Business Research Center) at Lappeenranta University of Technology, the Institute of Power Engineering at Tampere University of Technology and VTT Technical Research Centre have participated in the projects that constitute this thesis. 1.4.4. Limitations of the study This thesis provides a management concept for rural electricity distribution companies engaged in large-scale underground cabling of the existing overhead lines. Within the scope of the research there are issues such as: how to identify the emerging risks after a new regulatory ruling is issued, and how to manage these risks in particular when services are outsourced. The term management in this thesis refers to actions taken to handle or control the regulatory risk when outsourcing network-related services in the electricity distribution sector; it is emphasised that the focus is not on business administration. The research questions are extensive both in terms of what are the regulatory risks, whether outsourcing should be used and to what extent. The chosen research approach does not provide definite answers to how to manage risks arising from the economic regulation of the electricity distribution business. In network construction, the competitive landscape is found to be revolutionary, which gives grounds for a new approach to the network development strategy. Underground cabling is chosen in this study as it provides

28 28 weather-resistant networks and thereby provides a good solution to future expectations on the quality of electricity distribution services. Based on the data available in this study, outsourcing is found to be increasing in the electricity distribution sector in Finland. The risks of outsourcing services as such are left outside the scope of this study as they are already widely covered elsewhere in the literature (e.g. Hallikas et al. 2004, Hallikas et al. 2002). Therefore, this research considers sector-specific features of outsourcing. In this thesis, the term outsourcing is generally used to refer to a transfer of a business function or a significant part of it to an external service provider or to an independent business unit within the outsourcing company. 1.4.5. Outline of the thesis This doctoral thesis is organised as follows. Chapter 2 has three agendas. First, the chapter introduces special characteristics of the electricity distribution business that mainly attribute to the dual role of the electricity distribution networks, that is, delivering electricity to the endcustomers and facilitating the functioning of the electricity markets. While the attributes of the operating environment are in a decisive role for the electricity distribution business, the design and implementation of the regulatory system can be argued to have a great influence on the business risk experienced by the distribution companies. The regulation models have inherent properties that affect the risk and distribution of risk between the interest groups. The chapter finally discusses the theory of outsourcing. Chapter 3 elaborates on economic regulation and the role of a regulatory risk in the electricity distribution business in Finland. Electricity distribution is a highly capital intensive business, and the asset lifetimes are long, which emphasises the importance of preparing for the perceived risk. The aspects of the Finnish regulation regime are discussed by developing a systematic approach to analyse the risk components of economic regulation. Chapter 4 identifies the implications of regulatory risk for the network construction activity. Empirical evidence of outsourcing in the Finnish distribution business is applied in the work. Finally, Chapter 5 presents an operational principle for responding to and managing regulatory risks by employing specialised service providers. Chapter 6 provides the concluding remarks.
